Different parts of the US exemplify the full spectrum of tolerance to xenophobia. Our bests are pretty darn good (not near perfect), but the variance is high.
US law/regulatory policy may be a good measure, and is definitely less xenophobic than than of many/most European governments. The best example is what happens with refugees and immigrants, who are treated as interlopers in France; American policy is 'skeptical' of refugee claimants, but much more likely to permit them to settle and work if the claim is accepted.
To say nothing of the fact that their children born in America are natural-born citizens of the United States, unlike almost every other similarly industrialized/wealthy country (the Maple Leaf State doesn't count!).
As a brown guy with a beard, I’ve felt comfortable almost everywhere in the US I’ve been, including rural Illinois, Georgia, and Texas. In my experience, Americans are very uniformly warm and welcoming. Sydney I felt less welcome.
Yeah but come on (I fear I may be verging on no true scotsman territory here, but...) you're not culturally a brown guy, I doubt you even have a non-American accent (do you?).
I'm an American brown guy but I've often felt like an outsider. Having traveled quite a bit, some experiences that stick out in Germany and Iceland is random folks casually starting conversations with me, I struggle to recall this happening to me in America.
